Anchor bolt for boat motors



ed end l9 to be separated and nloved into binding engagenent vvith the threaded vva1l f the socket 2 as indicated by the heavy thread lines 20( in 'i ues 3 and the wed e ke 2l| Inov ing upwardly between the legs 23 When the shank l'l is screwed hoIne in the s0cket 20. 8 ShOWT1 in E'igure 1, the flange 2| on the driftbolt head |4 is engaged vvith the outer face of the hu11 0f the boat, the socket 20 0f the head extending through-an opening in the hu11 While the shank 0f the driftb01t l3 freely passes through the Inotor 1Tlounting b10ck l|.

In the forn1 0f invention illustrated in 'igureS 5 8nd 6 the flange carried by the Socket 2l iS disp0sed at an angle to the I1gitudina1 axis of the socket, the bottom face 2T of the flange being flat while the upper face theTe0f is of tapering 01' conica1 for!nation as at 28 f0` Seat ing in a recess forzned in the lower face of the hun m 0f the b0at with the flat face 2T of the iange flush with the outer face of the hu11 |D, the a nge being countersunk in the hu11.

t iS also intended t0 provide 9 10cking connection between the head l4 0f the driftb01t and the hu11 0f the b0t and as Shown in Figules 7 and 8, the socket 20 0f the head l4 c rries a head nage 29 having a flat face at the base of the socket 2 from which rises` a series of anchor pins 3 hile the outer face of the nange 29 is tapered or Of conical formation as at 3|- AS Shown in 'igure 7 the nat face 23 is engaged with the outer face of the hull Of the Ship, the pins 3u being driven in0 the hu11 m tO h01d the head l4 against rotation relative to the hull of the boat.

I'I-0Tn the above detailed description of the inventi0n, it is believed that the construction and 0peration there0f vvi11 at once be apparent, and wh le there are herein Shown and described the preferred en1bodi!nents 0f the invention, it is nevertheless to be underst00d that n]jT10' changes ma be nlade therein rithout departin fron1 the spirit and scope of the invention as clai!ned.

I claim:

A` driftbolt 0f the character described 00In prising a Shank having a threaded end, the threaded end of the shank being bifurcated, an internally threaded socketed head into which the bifu'cated end 0f the shank is threaded and a wedge key in the bifufcated end of the sha nk and normauy projecting beyond the end of the shank for engagenlent with the botton1 0f the S0cke in the head and adapted to spread the bifurcated ends of the shank when the latter is thralded int0 the head for moving the bifurcated ends into frictiona1 and binding engagement with the waus of the head socket, the bottom wall of the socket being 0 conical fornlation and the wedge key being of blade-lil{e form with the !1or!!1a1ly projecting end of v-shape incident t0 the conica1 Socket to' facilitate rotation 0f the vvedge key in the botton1 0f the socket and nlovement of the key in the bifurcated end of the shank during rotation of the shank in the socketed head KARL A AHLGREN
